GRAMMAR POINTS TO REMEMBER
- “Can” for Present Ability and Confident Offers:
- In the business world, when you write an email to a client, you want to sound strong, capable, and professional. We use “Can” to state exactly what our company has the power and ability to do right now.
- Example: “We can deliver the product tomorrow.” (This shows 100% confidence).
- Why not use “Could”?
- “Could” is often used for the past (“We could do that last year”), or for polite, hypothetical situations (“We could do that, if you really want…”).
- In a sales pitch or a list of company services, “could” sounds too weak, uncertain, or hesitant. “Can” is the standard modal for asserting positive capabilities to clients.
- The Grammar Rules (Never Forget These!):
- Rule 1: NEVER use “to” after can or could. (Say: We can help, NOT We can to help).
- Rule 2: NEVER add an “-s” to can, even for singular subjects. (Say: The team can help, NOT The team cans help).
- Rule 3: NEVER use “do”, “does”, or “are” with can. (Say: Can you help?, NOT Do you can help?).
